it's important to close requests asap. I've looked through the documentation but i'm not sure i have seen a reference to such a feature, does it exist ? Is this done using Timeout, or Wait ?
There is no knob in mathopd to turn off keepalives. The server will kill connections that are idle when a new request comes in. See the description for 'Clobber' in config.txt. You could set the value of "Wait" to a low number but I'm not sure if this is a good solution.
